Photoshopped version of my photo by unknown artist - I do not own the copyright to this derivative work

The original image

It was awhile ago, but someone sent me a photoshopped version of my photo of George Lucas and JJ Abrams. I can't seem to find the email. I'd like to contact the artist to ask for permission to use it and ask them to license it under a CC license. I'd also like to provide attribution. If you sent me the photo and are reading this, can you leave a comment or send me an email? If you know who did this, let me know too.
